The new Outlook

Microsoft is retiring its famous email client, Outlook. This is arguably overdue: it has long felt bloated and outdated.

The trouble is, Outlook has countless loyal fans who swear they could never use anything else: they shun the more streamlined web version of Outlook, which grew out of Hotmail, and refuse to believe that thousands of companies and millions of individuals actually use Gmail for real work.

But for better or worse, the choice is no longer in their hands. The Outlook we all loved (or hated) has been renamed Classic Outlook on Windows and Legacy Outlook on Mac, and no longer ships with new PCs, with a view to its eventual withdrawal as part of Microsoft’s roadmap to replace it.

What’s next?

If you use Windows, you might notice an app called Outlook (new) has been installed automatically. In time, it will be simply called Outlook.

The new Outlook has clearly been built from scratch, inheriting little from its predecessor. In fact, it looks and feels very much like the lightweight web-based Outlook (formerly Hotmail) mentioned earlier.

If your email account is with Microsoft – in other words, your email address ends in outlook.com, live.com, hotmail.com or hotmail.co.uk; or you use Microsoft 365 email as part of an organisation – the new Outlook should function well for you.

But for everyone else, there’s a notable devil in the detail that’s easily overlooked: Outlook is no longer an IMAP client. That is, it doesn’t directly connect to third-party email providers like AOL, BT, Google, TalkTalk and Yahoo.

Instead, when you add one of these accounts to Outlook, you’re actually giving Microsoft permission to maintain a connection to your email provider within its cloud infrastructure, and to cache a copy of your mail on its servers. Outlook then provides a view of those messages, and changes you make in Outlook sync via the Microsoft cloud back to your provider.

I foresee people being variously affected by this as follows:

Finally, it’s important to note that the new Outlook may not yet have some of the features you expect. If you’re a power user, you can check the roadmap to see what Microsoft plans to make available and when.

What are the alternatives?

If you currently use Outlook but don’t want to switch to the new version, broadly speaking you have two choices:
